Analysis and design of an impulse current generator

Abstract:- This paper presents an analytical method for the design and analysis of impulse current generators according to the requirements of the international standard IEC 60060-1. The circuit of the generator is analyzed and mathematical expressions for the most important circuit and impulse current parameters are included. The analytical expression of the impulse current waveform in the distinct operation conditions of the generator, as well as expressions for the calculation of the time constants of the waveform are computed. Moreover arithmetic expressions concerning the range of the generator element values are derived, ensuring that the characteristics of the generated current are in accordance with the limitations of IEC 60060-1. These expressions can well facilitate the correct design of the impulse current generator taking under consideration the international standard. A computer programme has been also developed to support the complex calculations in the impulse current generator circuit. The programme has the ability to calculate the desired configuration and the characteristics of the generated current
